This dramatic paleoclimate change – which was hallmarked with widespread auroras – could help explain other evolutionary mysteries, like the extinction of Neandertals.

Ancient relic points to a turning point in Earth's history 42,000 years ago | UNSW Newsroom
One of the major problems Creationist frauds have to cope with is the regularity with which natural records contradict their preferred time-line. One such series of records is that of frequent geomagnetic reversals, when Earth's North and South magnetic poles flipped. These events are recorded in the magnetic alignment of particles in the mid-ocean ridges, which record the polarity of Earth at the moment they solidified from the magma welling up from the cracks in the mantle as the tectonic plates pull apart.
Another is in the indirect record in the amount of radiocarbon preserved in ancient tree rings, which increases at the point of reversal as Earth loses the protection from solar radiation provided by its magnetic field.
These records, of course, contradict Creationism's childish claims of a young Earth of just a few thousand years old. This one shows a magnetic reversal about 40,000 years ago - some 30,000 plus years before the Universe existed, according to Creationists.
Scientist from the University of New South Wales, Australia, have found evidence of a period of major climate change associated with the last geomagnetic reversal 42,000 years ago - when Earth's North and South magnetic poles changed places. This period, which they have called the ‘Adams Transitional Geomagnetic Event’, or ‘Adams Event’ for short, after Douglas Adams of '
Hitchhiker's Guide to the Galaxy' fame. Douglas Adam's famously said the answer to life the universe and everything was 42!
This magnetic reversal was a period of mass extinction that saw the demise of the Neanderthals. Evidence for this change was found in the remains of ancient New Zealand kauri trees which have been preserved in sediment for over 40,000 years.
